BAG-FRAM E.

SPECIFICATION forming part Of Letters Patent No. 448,139, dated March10, 1891.

Application filed December 23, 1890. gerial No. 375,567. (No model.)

To whom it may concern.-

Be it known that BENJAMIN MAYER, a citizen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania,have invented a new and useful Improvement in BagFrames, whichimprovement is fully set forth in the following Specification andaccompanying drawings.

My invention consists of a bag or satchel frame having a springconnected therewith, substantially as described, whereby said frame maybe automatically opened and held opened, said spring being mounted onthe pivots of the frame and having its ends hearing against the frame,thus providing an inexpensive and practical device for the purposeintended.

It further consists of the combination of parts hereinafter described.

Figure 1 represents a perspective view of a bag having a frame embodyingmy invention. Fig. 2 thereof. Fig. 3 represents a vertical section of aportion at a right angle to Fig. 2. Fig. 4 represents a top view ofaportion, showing the ends of the spring concealed.

Similar letters of reference indicate corresponding parts in the severalfigures.

Referring to the drawings, A designates a bag, and B designates theframe thereof, said parts, excepting the feature of my invention appliedthereto, being of usual construction.

0 designates the pivot of the jaws of the frame, the same havingconnected therewith the wire springs D, a portion of each of which is ofthe form of a coil E, which is fitted on the pivot, and the ends F ofthe springs project from the coil in opposite directions and bear uponthe jaws of the frame, itbeing seen that when the jaws are closed thesprings exert pressure against the same in such manner that when thefastenings are released said jaws are forced open or apart and heldopen, as will be seen in Fig. 1. IVhen the jaws are closed, the ends Fride freely on the jaws, while the coils are contracted, so that thesprings exert the proper pressure on the jaws, whereby when the latterare released they are thrown open, as previously stated.

represents a vertical section In order to provide stability for the endsof the springs and increase the bearing-surface thereof, said ends arebentlaterally, forming lips G, which areincontact with the jaws, asshown in the several figures. The said lips G also present a roundedsurface to the jaws, thus lessening the liability of said ends beingcaught against the said jaws. The springs are prevented fromdisplacement by means of Washers or heads H, which are placed on theinner ends of the pivots and riveted or otherwise secured thereto, itbeing noticed that said pivots are made sufficiently long to connect thejaws, sustain the springs, and hold the heads. It will also be noticedthat both ends F extend from the same side of the coil of the spring atthe outer sides of the frame, so that the lines of their contact withthe jaws are substantially in the same plane, whereby there will be noliability of the ends leaving their seats on the jaws and entering thebag, the injurious effect of which would be evident.

In Fig. 4 I show the ends of the spring covered by plates F, said platesforming with the jaws closed chambers, the same concealing said ends,without, however, interfering with the freedom of motion thereof. Assaid ends of the spring are thus guarded, they are prevented fromcatching the contents of the bag or being caught by the same. The platesF are removed in Figs. 2 and 3 and the right side of Fig. 1.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

A bag-frame having pivoted jaws, a coiled spring bearing against thesame, having its ends projecting in opposite directions, andcovering-plates secured to said jaws, forming a chamber within whichsaid ends are located and have their play, said parts being combinedsubstantially as described.

BENJAMIN MAYER.
